[H]ard|OCP has assembled a review of the two best GPUs on the planet, in triplicate. It got off to a rough start as there is a serious issue with the last several Catalyst drivers, preventing you from using EyeFinity on Tri-Fire systems so they needed to revert to the release candidate that appeared back in January. The NVIDIA machine was easier to configure, once they realized that for triple surround they had to stay to one monitor per card. The PCIe lanes were provided by the ASUS P8P67 WS Revolution, which allowed these cards to really show off their stuff. Make sure you check out the power consumption page, you may be very surprised at how little power the GTX680s needed to run.

"What do you get when you install three GeForce GTX 680 cards for 3-Way SLI and then three Radeon HD 7970 cards for Tri-Fire? You get insanely fast gaming performance and a gameplay experience that begs to be compared delivered by both. We find out which multi-display configuration is better for gaming in Eyefinity and NV Surround."

Not too long ago [H]ard|OCP examined the price to performance ratio between a triple SLI GTX580 system and a Tri-Fire HD6990 and HD6970 and discovered that as far as value goes, NVIDIA could not touch AMD. A reader of theirs inquired if it was the aging Core i7-920 that was holding the cards back even with the overclock of 3.6GHz. A SandyBridge system with a Core i7-2600K and an ASUS board with the NF200 bridge chip was used to revisit the performance of the two vendors GPUs. The result; we can hardly wait for the Z68 boards to come out!

"We have re-tested performance between GTX 580 3-Way SLI and Radeon HD 6990+6970 Tri-Fire with a brand new Sandy Bridge 4.8GHz system. Our readers wanted to know if the CPU speed would improve performance and open up the potential of this triple-GPU performance beasts. To put it succinctly, they were right. The results completely turn the tables upside down and then some."

[H]ard|OCP just finished a review that most enthusiasts would sell their souls ... or at least cash in their retirement savings ... to do themselves. They decided to find out which was better, a $1500 triple GTX 580 system or a $1100 HD 6990 + HD 6970 system. The findings are really quite clear, as is th efact that scaling has improved to the point where dropping that third GPU into your PC actually does make some sense to do.

"We've seen what a Radeon HD 6990 can do when paired with a Radeon HD 6970 for "Tri-Fire" performance. Now it is time to find out what three NVIDIA GeForce GTX 580 video cards in 3-Way SLI game like in comparison. We will look at A2A performance comparisons and discuss which setup offers the best gameplay experience."
